Building Material Microscale Combustion Calorimeter BS EN 746-2 ASTM D7309

Building Material Microscale Combustion Calorimeter BS EN 746-2, ASTM D7309

Introduction:

It can determine the basic thermo-chemical data, such as Specific Heat Release rate, combustion calorific, Ignition Temperature, by testing very little specimen (1-10mg) in a few seconds, and predict the combustion retardant characteristics of the tested material.
